This invention relates to lead alloys to be used in the chemical industry. 7 I

A lead alloy according to the present invention is of the usual compact, non-porous, structure, 5 and comprises from 0.3 to 13% Sb and from 0.2

c to 5% Kg.

Moreover, the alloy may contain one or more of the metals Zn, Ca, 31:
